If you're using connectSlotsByName (which the .ui file produces), you HAVE to 
pay attention to slot naming.

It's on_<objectname>_<signalname>.

If you name anything starting with "on_", you have to do it the whole way. And 
don't connect manually, like you did below. Just leave the the automatic 
connection to take place.

Or don't name your slots starting with "on_".
